Key Features in iOS 15

1. FaceTime Enhancements

FaceTime received significant upgrades designed to make video calls feel more natural:

• Spatial Audio: Spreads out voices to sound like they are coming from the direction of the speaker on the screen.
• Voice Isolation and Wide Spectrum: Filters out background noise to prioritize voice clarity or captures all ambient sound when desired.
• SharePlay: Allows users to watch movies, listen to music, or share screens synchronously during calls.
• Cross-Platform Links: Enables Windows and Android users to join FaceTime calls via a web browser.

2. Focus and Redesigned Notifications

iOS 15 introduced Focus, a feature that filters notifications and home screen pages based on the user's current activity, such as working, sleeping, or personal time.

Notifications were redesigned with contact photos and larger app icons for easier identification. A new Notification Summary feature collects non-urgent notifications and delivers them at scheduled times throughout the day to reduce distractions.

3. Live Text and Visual Look Up

Using on-device intelligence, Live Text recognizes text in photos, screenshots, and the live camera viewfinder. Users can copy, paste, look up definitions, make phone calls, or translate text directly from an image. Visual Look Up allows users to learn more about popular art, landmarks, nature, books, and pet breeds captured in photos.

4. Safari Redesign

Safari received a modern interface that shifted the tab bar to the bottom of the screen for easier one-handed navigation. It also introduced Tab Groups, allowing users to save and organize tabs across different devices, as well as support for web extensions.

5. Privacy Protections

iOS 15 strengthened data protection through several tools:

• Mail Privacy Protection: Hides user IP addresses and prevents senders from seeing if an email was opened.
• On-Device Siri Processing: Ensures voice requests are processed locally without an internet connection for improved speed and privacy.
• App Privacy Report: Gives visibility into how frequently apps access locations, photos, cameras, microphones, and network domains.

Device Compatibility

Apple maintained broad support with iOS 15, allowing it to run on all devices capable of running iOS 14. This includes the iPhone 6s and newer, the first- and second-generation iPhone SE, and the seventh-generation iPod Touch.
